#include <cstdio>
inline int read() {
register int x = 0;
register char ch = getchar();
while (ch < '0' || ch > '9') ch = getchar();
while (ch >= '0' && ch <= '9')
x = x * 10 + ch - '0', ch = getchar();
return x;
}
int main() {
int n = read();
return 0;
}
如果输入文件中没有输入,这个程序就会陷入死循环,请问怎么办?
NOI Online爆零会不会也是因为这个?
